SPECIFICATION forming part of Letters Patent No. 760,318, dated May 17,1904.

Application filed February 11, 1903. Serial No. 142,838- (No model.)

To a whom it may concern:

Be it known that we, WILLIAM KENNEDY- LAURIE Dronson, a subject of theKing of Great Britain and Ireland, and GIUsErPE AN- TONIO Gnooo'rrr, asubject of the King of Italy, both residents of London, England, haveinvented certain new and useful Improvements in Engines, of which thefollowing is a specification.

Our invention relates to engines or motors, and particularly to thatclass of such engines or motors as are usually termed revolvingcylinderengines.

The principal objectof our invention is to provide a simple andeflieient motor occupying but small space in proportion to the amount ofpower developed by the same, whereby it is particularly adapted for usein motor-cars, automobiles, and in all cases where the utmost economy ofspace is desirable, although our improved motor is by no means limitedto such uses, being capable of advantageous employment in many otherways.

A further object of our invention is to overcome various defects whichhave heretofore been present in engines of the class referred to.

Our invention consists of the novel construction, arrangement, andcombination of various devices and parts, as hereinaftermoreparticularly described.

In the accompanying drawings, Figure 1 is a transverse vertical sectionacross the motorcase; Fig. 2, a longitudinal vertical section; Fig. 3, ahorizontal section, and Fig. 4 a top view of the controllinglever andcertain other parts, all as hereinafter particularly referred to andexplained.

In carrying our invention into effect we provide a casing comprising anannular portion 11 and sides 12 12, the whole being supported by abase13. The sides 12 12 are perforated to allow the passage of the shaft 14and the plug 15, hereinafterdescribed. Four cylinders 16 are provided,which may be integral with each other or otherwise, but in either caseare rigidly attached together in the form of an X, each cylinderconstituting one arm thereof. The shaft 14 projects from one side of thecylinder structure, and intothe other side and nearly transverselythrough the cylinder structure passes the plug 15. The inner end portionof the said plug is tapering, and means are provided, as hereinafterdescribed, for keeping the plug always sung in its socket. A bushing orsleeve 33 is provided intermediate the plug and the cylinder structureprovided with openings 8.

Each cylinder has at its inner end an aperture 18, which opens into thecentral opening, in which lies the plug 15. The cylinders are open attheir outer ends. Each cylinder contains a hollow or cup-shaped piston19, the outer portion of which bears a cross-arm 20, to each end ofwhich is attached a rod 21. The cylinders are provided with slots 22,into which the cross-arms 20 pass when the piston moves toward the innerend of the cylinder.

Suitably rigidly secured to the inner sides of the casing are eccentrics23, around each of which is placed an eccentric-strap 24. The inner endsof the rods 21 are pivotally attached at four equidistant points to thestraps 24:. The said straps are connected by arching bridge-pieces 10,tending to keep them revolving always at equal speeds.

Theplug 15 is hollow and isprovided with a longitudinal partition 25,which divides the .interior into two chambers, (designated in thedrawings 26 and 27.) Each of these chambers has an opening at each end,the four openings being designated 28, 29, 30, and 31. The function ofthese openings will be hereinafter fully described. A partition lSextends downward from the rear or inner portion of the longitudinalpartition 25, and through this partition 48 are drilled a number ofholes or channels 411, which enter a channel 19, drilled longitudinallythrough the partition 25. These channels 49 and 17 are for containinglubricate ing-oil and conducting the same to the bearing-surfaces. Theplug 15 is free to turn on its axis and bears at its outer end a lever32 for so turning the same. Any suitable means may be provided-as, forinstance,.. those shown in Fig. 1--for holding said lever, andconsequently said plug, 111 any des1red,pos1- tion. The plug is taperedat its outer end also, and fitting closely over the same is acorrespondingly interiorly tapered sleeve 40, provided with anupwardly-extending pipe L1 and a somewhat larger downwardly-extendingpipe 42. This sleeve 40 is provided with two lateral lugs 4.3. (See Fig.4.) From the front of the casing extend forward two rods 44, which passthrough perforations in said lugs and are provided at their outer endswith nuts 45. Between said lugs and said nuts are helical springs 46,tending to keep said sleeve always pressed firmly in upon the taperingend of the plug and to keep the plug itself snug in its seat in thecylinder structure.

The operation of our invention is as follows: The opening 28 beingconnected with a source of supply of steam or other motive power, thesame passes through said opening into'the chamber 26 and out of saidchamber through the opening 29 into such one of the cylinders as may atthe time have its opening 18 in communication with the opening 29.Should neither cylinder happen to be at the time in such communication,a slight movement of the lever 32 will turn the plug sufficiently tobring it into a position in which such communication shall take place.The steam of course tends to force the piston outward toward the end ofthe cylinder, and thus exerts a pull upon the eccentrics, which causesthe cylinder to move sidewise-toward the point where the rods areattached to the eccentric. As the cylinder moves its aperture 18 passesout of communication with the opening 29, and the influx of steam intothe cylinder ceases, and the steam then works expansively during theremainder of the stroke. When the cylinder has made a half-revolution,the opening 18 is brought into communication'wth the opening 30 of theplug, and the steam in the cylinder passes out into the chamber 27 andthence into the open air through the exhaustopening 31. It will ofcourse be understood that when the cylinder which first receives thesteam moves one-quarter of a revolution the second cylinder has beenbrought into position to receive steam and that this second cylinder anditspiston then-aid in the work, and that when the first cylinder hasmade onehalf of a revolution and is in position to exhaust the thirdcylinder is in position to receive steam, and so on. V a

It will be evident that the direction of the revolution of the cylinderstructure and its shaft will depend upon the direction in which theopening 29 of the plug is made to face and upon which one of thecylinders the steam is first caused to enter. 1

The advantages of our invention are obvious. We would particularly callattention,

however, to the fact that as the plug 15 is tapered and spring-pressedit is always steamtight, that the work of the pistons is done by meansof pulling only, thus minimizing friction, and to the simple andefiicien-t throttle cut-off device which we have provided.
